2020-12-01 · Since the 1980s, the University of Washington carotid duplex criteria have been widely used and modified in vascular laboratories throughout the world. Additional clinically relevant criteria have also been developed, such as a threshold for the 70% to 99% North American Symptomatic Carotid Endarterectomy Trial (NASCET) stenosis.



Methods and Results— We analyzed 39 patients (40 CAs) who underwent CA stenting with baseline and 6-month follow-up carotid duplex ultrasonography and intravascular ultrasound. Intravascular ultrasound measurements included minimum luminal diameter 2021-04-02 Optimal depth and focus setting for carotid (Duplex) ultrasound/sonography at a depth of 2,5cm. Note that the common carotid artery is seen “full screen” - still the depth is set in such a way that structures approximately 1 cm posterior to the common carotid artery are still visible. The focus point is at the level of the carotid artery. The Carotid Duplex Exam section will: Discuss the 2D/B-Mode, color and spectral Doppler images required for a complete bilateral exam; Describe the technique for obtaining optimal pulsed wave spectral waveforms; The Carotid Stenosis section will: Recognize the different techniques needed when carotid stenosis is present; Describe the grading of 2013-06-01 Background: The optimal duplex ultrasound (DUS) velocity criteria to determine in-stent carotid restenosis are controversial.

Duplex scan to evaluate for carotid artery stenosis is considered medically necessary for ANY of the following indications: Carotid stenosis is a risk factor for ischemic stroke. Imaging for CAS includes duplex ultrasound, CTA, MRA, and catheter angiography, but ultrasound is usually the preferred initial imaging modality. The presence of atherosclerotic plaque in the carotid artery is a predictor for future risk of cardiovascular disease. But when the amount is not severe, the focus is on drug treatment, not surgery. Progression is associated with a number of factors, including diabetes and smoking. The initial amount of blockage is important, too. Carotid stenosis, or carotid artery disease, is a narrowing or blockage of the carotid arteries.

Ultrasound of carotid arteries is a duplex ultrasonography that has the ability to image as well as measure the flow rate in the vessels. With this analysis it is 

Carotid Duplex Ultrasound Ultrasound is a study that uses sound waves to "see" inside your body. A carotid duplex ultrasound is performed to evaluate symptoms including dizziness, loss of memory, stroke, loss of musclecontrol and other symptoms that might result from narrowing or blockage of the vessels (carotid arteries) on either side of your neck. Duplex ultrasonography of the internal carotid arteries (ICAs) is indicated in several clinical settings, including patients who have experienced transient ischemic attacks, patients with ischemic stroke, and asymptomatic patients who possess cervical carotid bruits, and as a preoperative evaluation before coronary artery bypass graft surgery or aortic valve replacement. Carotid duplex ultrasonography is largely used as a first line diagnostic tool for carotid stenosis in symptomatic and asymptomatic patients. The decision to offer surgical inter-vention is often dependent on duplex velocity in addition to patient presentation. Computer tomographic arteriography Spectral waveforms were correlated with carotid arteriograms (PSV, EDV, spectral broadening) Bi-planar, cut films, measured with calipers Estimated carotid bulb diameter used as the reference site Large categories of disease (ranges of stenosis) Phases I, II, and III ( 1979 to 1984) CAROTID DUPLEX … Two meta-analyses provide information on the accuracy of carotid duplex ultrasonography in detecting clinically important stenosis.4, 5 Recent systematic reviews of studies about the accuracy of A complex duplex carotid evaluation involves high resolution imaging and characterization of the carotid plaque as well as quantitative Doppler spectral analysis to determine the presence and degree of flow restriction. Each of the components of the examination is essential to evaluate the carotid arteries adequately for the presence of disease.
